"Baby Chicago," she captioned the picture, which had received over 6.1 million likes on Instagram as of Tuesday morning.
Kardashian and West welcomed Chicago via surrogate Jan. 15.
The reality star said in a tweet Saturday that Chicago looks "a tiny bit" like her other two children, 4-year-old daughter North and 2-year-old son Saint.
"[Chicago is] the sweetest! Best baby! She looks a tiny bit like North and a tiny bit like Saint but definitely her own person!" she wrote.
Kardashian said Saturday at the Create & Cultivate event in Los Angeles that she stays "present" as a mom by ignoring her phone when she's with her kids.

"One of the rules I have about being present with my kids is I don't have my phone when I'm with them," she said, according to People. "So, like story time at night, in the mornings getting ready, I just don't have my phone."
"I want my kids to see the separation and to feel the difference and know that there is a time and a place for that," the star explained.
"So I'm really cautious when I'm at home with my phones and just being super present."
